It is a current feature (multi-view), but you have to wear glasses - the frames sych at the same time rather then left/right for 3D - the sound is also an issue too...
Performed a little research to find the name they use for this feature and found this article - they say 10 (OLED) differrent shows and Samsungs glasses shown in the article have built in sound... www.smithsonianmag.com/innovation/people-can-now-simultaneously-watch-different-shows-on-the-same-tv-180947762/
I think one of the main issues is resolution and field of view. When you are looking at 3D for it to be real looking you need to have a wide field of view which is very hard to to in anything but a theater. Of course source material is also an issue although resolutions is is incredibly getting better and better - 4K is incredible after just these few years.
Actually though I think the underutilized function of 3D is that switching in that you can show two totally different shows - need to figure out the autio better - and I remember seeing 3 different shows from the same TV on a TI micro mirror display.
Now that we all want different programming and we want it NOW you either leaver the room and watch on you TV, Ipad, Phone or whatever.... Makes watching TV more of an individual experience then it used to be a few years ago...
oh yes, and one more thing. A new trend is making the "touch screen" in a car as close as to that of media tablets. You don't want the car display to be something as primitive as "push here button" type of touch screen, but rather much more fluid as that of tablets.
It's obvious, but it means a boon to touch screen companies!
Between wearable devices and car infortainment, the latter has better chance to boost display market growth. Wearables will have smaller display and will be full of high end mems sensors and IC devices. However the car infortainment will need high end display devices and touchscreens for entainment purpose. Also the flexible displays can find better market in automobiles than anywhere else.
